Saline mushrooms (multiple edible species) include at least 86 types that naturally grow in salty soils and coastal zones where normal crops fail. These mushrooms maintain high protein, fiber, and antioxidant levels even at salt concentrations that kill most plants, and some species tolerate salinity close to seawater. This means future food could be grown on salt-damaged farmland using brackish water instead of fresh, expanding protein production as climate change increases soil salinization.
